BICYCLE-BRAKE.

SPECIFICAIION forming part of Letters Patent No. 662,553, dated November27, 1900.

T0 au wh07n it may c0nccrn:

Be it known that I, WILLIAM GRIFFITEIS TASSELL, asnbject of the Queen ofGreatBritain, and a residentof Voolwieh, London,England, have inventedcertain new and useful Improvements in Brakes for Velocipedes, (forwhich I have applied for a patent in Great Britain, No. 11,872, datedJune 7, 1899,) of which the following is a full, clear, and exactspecification.

This invention consists of improvements in or relating to brakes forVelocipedes.

In carrying out myinvention I provide a spring-piece or grip which isattached to a suitable part of the frame of the machine, so that thegrip may be readily operated at or about the rear of the saddle. Iprovide two braking-snrfaces which engage upon either side of the rin1of the rear or driving wheel and which are provided With suitable beauings for the pnrpose of sliding or moving upon the forks carrying thisrear or driving wheel. These braking-surftces are connected through themedium of a rod or rods to the spring-piece or grip aforesaid. When itis required to apply the brake, the spring-piece or grip aforesaid isoperated by the hand of the rider, so as to bring the braking surfacesor bloeks into contactwith the rim of the wheel and so retard the motionof the machine. I find that by this arrangement I can provide a lightbrake which I can arrange so as not to be obtrusively visible, as manyriders object to the ordinary lever-brake 0perating upon the tire of thefront wheel.

For purposes of illustration I Will now refer to the annexed drawings,in which Figure 1 is a side elevation showing my in vention applied tothe rear wheel of a bicycle; Fig. 2, a side elevation of a modifiedarrangement; Fig. 3, a section through line X Y in Fig. 1.

a is a collar or clip having curved ends Z) attached to the tube 0through the medium of the set-screw d. This collar or clip a carries thespringrod e,bent as shown, and upon which the rods or bars f, formed ofwire or other suitable material, are carried at 9. The ends of theserods or bars are adjustably attached to the brakingsurface h through themedium of the block 7), guide j, and securing bolt or screw 70. Thisblock 75 and guide j spring-rod e.

slide upon the frame-bar Z. The brakingsurface may be formed of anysuitable material, such as leather, this being attached to the block 73in any convenient manner.

Referring t0 Fig. 2 in this case, the braking-surlace 71 is carried uponthe support, pivotally connected at m to the clip n, s'ecured around thetube or rear fork 0 of the machine. The rod or bar 1) is adjustablyconnected to the, support, carrying the braking-surfaces h, as shown,and also to the It will be seen that by moving the spring-rod e in thedirection of the arrow 1 the brake-surface 71 may be applied to the rimq of the wheel. The particular function of the springrod is that itmaintains, owing to its elasticity, the braking-surface from contactWith the rim of the wheel until applied by the hand of the rider, andwhen release'd will again withdraw the surface from contact.

Having thus described my invention, what I claim, and desire to secureby Letters Pat eut, is-

1. In brakes for velocipedes of the class herein described, incombination, a block or holder carrying the braking-surtace, rodsadjustably attached to said block, a spring bar or rod bent to therequired shape and to which said connecting-rods are attached, a clipcarrying theends of said bent rod 01 bar, said bloc]; being attached toa clip or baud adapted to slide upon the bearing or tube, substantiallyas deserbed and illustrated herein and for the purpose set forth.

2. In brakes for wheels et the class herein described, a spring rod orbar attached to the frame of the machine, a rod attached to the springrod or bar aforesaid and carrying a braking-surface adjustably attachedthereto,

a collar or clip pivotally carrying the braking-surface,said collar orclip being secured t0 a suitable part of the frame of the machine,substantially as described. and illustrated herein and for the purposcset forth.

In testimon that I claim the forcgoing I have hereunto set my hand this12th day of August, 1899.
